inwardly from opposed sides in said opening are the triangular walls 24 and 25, between which the discharge plate or shutter 26 is operable. This plate has trunnion pins 27 and 28 extending from the opposite edges thereof and journaled in the apexcs of the walls 24 and 25. Each wall has a longitudinal pocket 29 for receiving a latch member 30 secured to the respective trunnion pin. Above the pocket in each wall is a spring pressed latch plunger 31. These plungers cooperate with the eccentric pro jections 31 or the latch members 30 to yieldingly lock the discharge plate 26 against either of the opposite edges E or E of the opening 23.

Surrounding the outlet opening 23 and extending inwardly from the wall 19 is a scoop frame having the opposite scoop ends 32 and 33. The scoop frame is secured against the wall 19 by its flanges 34, the inner walls 35 and 36 of the scoop sect-ions being separated by a space or passageway 37 in which the inner end of the discharge plate 26 swings to engage either against the wall 35 or the wall 36. The scoop frame engages against the triangular wall 25, as shown in Fig. 5, so that each scoop end together with the discharge plate 26 will form a scoop or discharge passageway to the outlet 23. hen the discharge plate 26 is in the position shown in Figure 2, and the attachment is driven in counterclockwise direction (from the left of Fig. 2), the burnished objects will be taken up at the periphery of the drum 16 and transmitted through the scoop part 33 to the discharge plate 26 and from them out through the discharge outlet 23. hen the attachment rotates in a clockwise direction, the scoop section 32 will gather up the burnished objects and will transmit them to the discharge plate 26 and through the outlet 23, the plate 26 having been swung over into engagement with the edge It and with the edge of the wall section Any objects gathering in the scoop sections behind the discharge plate 26 will fall back into the drum through the space 37.

In order to entirely close the outlet 23 so that the objects can be retained in the riddle drum until all the burnishing balls have been separated, I provide a door or cover plate 39 for the discharge outlet 23. This cover plate may be hinged to the outer end of the discharge plate 26 to be swung in either direction to close the discharge outlet 23. When it is desired to discharge from the riddle drum, the cover plate 39 is swung away from the discharge outlet and locked in the dotted line position shown in Figure 2. In order that this discharge plate 26 may be readily set for left or right hand discharge, the trunnion shaft 28 has the extension 40 provided with a handle 41.

In order to facilitate the collection of the burnishing balls or other material as they fall through the riddle drum opening, I surround the riddle drum by a casing which receives the burnishing material and from which it may be readily discharged into a receptacle. A flange or conical frame 42 is secured to the base 13 by means of screws 43 and from this frame or flange extends sheet metal frame work comprising the inner section 44 and the conical section 45. The section 44 is secured at the inner end through the frame 42 and the outer end of the section 45 is secured to the end frame 19 of the riddle drum. The frame 42 has the L-shape extension 46 surrounding the part 44 and at its inner end, the part 45 has the flange 47 secured to the outer edge of the extension 46 so that an annular trough 48 will be formed around the part 44. In this part 44 there is a discharge gap or opening 49 (Fig. 4), and diametrically opposite this opening the wall 46 has the discharge outlet 50 from the trough 48. As the separator attachment is rotated, the burnishing balls or material fall from the riddle drum into the collector casing and travel down through the passage 49 into the trough 48 from which they are discharged into a suitable receptacle from the outlet 50.

The separator attachment can be of light construction so that it can be readily handled by one man. The attachment eli'ects considerable saving in time and labor as it requires just a short time to secure it in place on the burnishing machine barrel whereafter separation, riddling and discharge of the burnishing material and burnished work will be accomplished entirely automatically. Changes in modifications can, of course, be made which will still come within the scope of the invention, and I do not, therefore, desire to be limited to precisely what I have shown and described.

I claim as follows:

1. Inca separator structure, the combination of a perforated drum having an inlet at one end for mixed large and small objects to be separated, there being a dis charge outlet at the other end of said drum of less width than said drum, a scoop structure for scooping up the larger objects when the drum rotates in one direction, another scoop structure for scooping up the larger objects when the drum rotates in the opposite direction, a discharge plate adjustable to connect either one of said scoops With said discharge outlet, and means for rotating said drum, the smaller objects falling through the drum perforations.

2. A separator structure con'iprising a riddle drum, a supporting base for the drum adapted for supporting the inlet end of said drum to receive a mixture to be 1,586,560 I I I 3 separated, a discharge outlet'at the other end of said drum displaced from the drum periphery, a discharge scoop for transmitting the larger objects from the drum periphery to the discharge outlet, a casing surrounding said drum for receiving the smaller objects through the drum openings, said casing having a discharge outlet, and an annular trough on said base connected at one side With said casing discharge outlet and having an outlet at its opposite side.

, 3; In a separator structure, the combination of a perforated drum having an: inlet at one end for large and small objects to be separated, there being a discharge outlet in the other end of said drum of less Width than said drum, a scoop structure adjacent to said discharge outlet having a scoop inlet'at each side and having an opening in its inner Wall opposite to the discharge outlet, a discharge plate Within said scoop structure between said discharge outlet and opening, said discharge plate in one position opening one of the scoop inletsto said discharge outlet and closing the other scoop inlet, said other scoop inlet being then in communication With the interior of the drum through saidopenin 4.
